From 9110d1b0e229cebb1ffce0c04db2b22beffd513d Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Sun, 20 Oct 2019 17:30:06 +0200 Subject: ASoC: msm8916-wcd-analog: Fix RX1 selection in RDAC2 MUX According to the PM8916 Hardware Register Description, CDC_D_CDC_CONN_HPHR_DAC_CTL has only a single bit (RX_SEL) to switch between RX1 (0) and RX2 (1). It is not possible to disable it entirely to achieve the "ZERO" state. However, at the moment the "RDAC2 MUX" mixer defines three possible values ("ZERO", "RX2" and "RX1"). Setting the mixer to "ZERO" actually configures it to RX1. Setting the mixer to "RX1" has (seemingly) no effect. Remove "ZERO" and replace it with "RX1" to fix this.

This will cause problems if the HDA link is freed with snd_hdac_ext_bus_link_put() while the codec is still in middle of its resume process. To fix this, change the order such that pm_runtime_disable() is called before the link is freed. This will ensure any pending runtime PM action is completed before proceeding to free the link. This issue can be easily hit with e.g. SOF driver by loading and unloading the drivers.
